“…Currently, the theory of analog ARC filters, including for ADC conversion tasks, is developing in the direction of the application of new active elements (AE) [18][19][20] (differential difference operational amplifiers [21][22][23][24][25][26], various modifications of current conveyors [27][28][29]16] and amplifiers with current feedback [30][31][32][33]). Active research is being carried out in the field of tunable filters [1,4,3], as well as in the direction of searching for architectures that minimize the influence of the gain area of the AE on the main parameters of the ARCF [34].…”

A new structure of the second-order lowsensitivity active RC filter (ARCF) with an extended frequency range is proposed. The ARCF circuit is implemented on three operational amplifiers (OA) and is recommended as a universal link in the construction of bandpass filters, as well as anti-aliasing low and high pass filters for operation in structures with analog-to-digital converters (ADC). It is shown that, due to the introduction of a new connection, additional difference coefficients appear in the transfer function of the ARCF under consideration, depending on the gain areas (GA) of the OA, which enables to reduce the effect of the frequency properties of the OA on the realizable characteristics at low power consumption. The circuit design of a low-temperature radiation-hardened OA on complementary junction field-effect transistors, designed for operation in severe conditions, is considered.

“…The operational floating current conveyor (OFCC) [1] is a variant of current conveyor with attractive features of both high and low impedance at input and output ports which make it suitable for sensing both currents and voltage and providing the sensed variable in form of current and voltage. The OFCC has been used to develop variable gain amplifier [1], basic amplifier circuits (voltage, current, transimpedance and transconductance) [2][3][4], filters [5][6][7][8][9][10], instrumentation amplifier [11], [12], readout circuits [13], logarithmic amplifier [14], rectifier [15], and wheatstone bridge [16] in recent past.…”

This contribution puts forward a new voltage mode instrumentation amplifier (VMIA) based on operational floating current conveyor (OFCC). It presents high impedance at input terminals and provides output at low impedance making the proposal ideal for voltage mode operation. The proposed VMIA architecture has two stages - the first stage comprises of two OFCCs to sense input voltages and coverts the voltage difference to current while the second stage has single OFCC that converts the current to voltage. In addition it employs two resistors to provide gain and imposes no condition on the values of resistors. The behavior of the proposed structure is also analyzed for OFCC non idealities namely finite transimpedance and tracking error. The proposal is verified through SPICE simulations using CMOS based schematic of OFCC. Experimental results, by bread boarding it using commercially available IC AD844, are also included.

“…The operational floating current conveyor (OFCC) [23,24], which was introduced as operational floating conveyor (OFC) [25], combines the features of current conveyor and the current feedback op-amp along with additional current outputs that add flexibility in the circuit design. Literature survey on OFCC based circuits [26][27][28][29][30][31][32] shows that voltage mode filter [26][27][28], variable gain amplifier [29], wheatsone bridge [30], and instrumentation amplifier [31] and read out circuit [32] are available. The study of current mode filters [1,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] shows that no OFCC based current mode filter is available in the literature.…”

This paper presents operational floating current conveyor (OFCC) based single input four output current mode filter. It employs only three OFCCs and two grounded capacitors and resistors each. The MOS based grounded resistors implementation is used, which adds feature of electronic tunability to the filter parameters. The filter also enjoys low component spread and low sensitivity performance. The effect of finite transimpedance and parasites of OFCC on the proposed circuit is also analyzed. The functionality of the proposed circuit is demonstrated through SPICE simulations using 0.5 µm CMOS process model provided by MOSIS (AGILENT).
